3 decimal places (1 mm) should be plenty precise, i would think. any preferred scaling parameter? charge/current ratio? (on that note, anybody know how to convert "voltage on the grid" to charge density (columbs/meter))?rjaypeters wrote:6-coil circular six coils:

Regular polygons? As good as I can do.

i hate to say it rj, but from the simulation it looks like you've got at least one of the current loops backwards. the electrons spiral and go in the same direction which suggests you have a pair of facing (e.g. opposite) coils with the same polarity.
(my first attempt had problems like this too, btw.)

Huh. I'll check, but I thought I was careful to maintain counter-clockwise as seen from outside! Apologies and thanks.
Edit:
100% checked. Found one error in third(?) ring. Lesson learned: I won't post until I do a 100% check.
Also, if some wish to join the fun, I will happy to post my models.

maybe start w/my cuboctahedron (every 4 lines is a coil), which i know is correct 'cause i've tested, and push the coils out from the center to get the desired coil separation, then slice each segment into 2, then 4.
i'm going to see if i can get particle sources and sinks working over the weekend. then we can actually see electrons with the right KE per radial displacement.

i just made a 16-gon approximation of a wb-6 with unit-radius coils and no coil separation. just tell me what the distance of a coil should be from the center to get the desired separation and i'll plug it in using "find and replace".
and just for the hell of it,
which, judging from this picture, is all the precision we could ever possibly need.

k, i made a 32-gon unit wb-6.
what should 0.000000a = ? (the major radius of the containment sphere) what should the spatial scale be? other parameters (electron gun distance from center, initial electron velocity, etc., coil current density, coil charge density, etc.)

Triangles:
I am using a sphere 1.5m in radius and the coil centers are 1.273m from the origin (the number that doesn't change in the examples above).

wb-6 style, distance from coil midplane to origin 1.1 times coil radius. (giving a decent amount of coil separation) electrons start as a hollow sphere. you can make out some weak line cusps due to the coil separation and the fact that the coils are circular (actually 32-gons).

Understood it is still a ways off. But you have definitely kicked open the door for using a GPU to sim a Whiffleball.
Indeed, interesting simulation. The bright spikes with only faint (?) bridges between the corner (virtual point) cusps would support my assumption that these cusp losses are greater than the 'funny' linear cusps between the closest approaches of the magnets. Of course I realize that this is an evolving model and may change. In any case it is intriguing to see the shape in a rotatable 3 dimensional representation as opposed to a 2D representation. Good work and keep it up.
